Question

What is the name for the layer of air molecules that forms along the surfaces of a moving object, such as a car?

Answer 1

Answer:

Explanation:

The thin layer of air closest to the surface of a moving object is called the boundary layer. This is where friction drag occurs. The boundary layer is a very thin layer of air flowing over the surface of an object (like a wing). As air moves past the wing, the molecules right next to the wing stick to the surface

Answer 2

The name of layer along the surface of moving object is called Boundary layer

• In boundary layer the particles of air sticks to the surface of moving object causing friction

• The velocity of air at the surface of object is zero and it goes on increasing as we move away from the object

• In boundary layer Bernoullis equation cannot be applied

• The width of boundary layer goes on increasing as the air moves towards the moving object

• The boundary layer width decreases if the velocity of air is increased
